Aiming at multi-parameters

wide surveillance range

high requirement for real-time performance

difficulty in wire system alignment and vulnerability of highway healthy monitoring system

an embedded road health monitoring system with wireless transmission is designed.Three-layer structure design is used in the proposed system

consisting of data acquisition node

relay node and monitoring center

multi-sensor integration technology

MCU intelligent control technology and KingView control system are utilized in both hardware and software construction

and inter-layer communication is carried out using wireless radio frequency technique and data transfer unit（DTU）

finally realize real-time information acquisition and processing of temperature

humidity

pressure

strain

and acceleration in embankment.Preliminary experimental result shows that the whole system works stably and reliably within 4 km

which can meet needs of highway monitoring transmission of mid-and long distance.
